Schiit Lokius anyone?

I waited over 3 months for my +.
Got it a few weeks ago.
Added it between my pre and amp using the same type high quality interconnects.
I like it!  The wife likes it!
I feel it was a good addition to my system...

I waited literally months for my Loki+.  
Excellent packaging and impressive looking build quality.
Hooked it up in and out with high quality Audio Quest King Cobra interconnects.
Plugged it in to my dedicated 12/2 20amp quad set of Audio Quest hospital grade, cryo treated 20 amp outlet.
Turned it on... immediately a bad hum occurred, it also runs hotter than my C-J premier 17 ls tube pre amp.  
Shut it off or bypass and the hum disappears.
Contacted C.S.  Took 5 tries to get a R/A to ship back for them to look at.
Wish me luck.....
